Java Break

break immediately leaves the nearest loop or switch. In a loop, remaining rounds stop. In switch, later cases do not run.

A common pattern: search an array; when you find the value, break. No need to keep looping. continue is different: continue skips one round; break ends the loop.

In nested loops, plain break exits only the inner loop. If you expected both to stop, that is a mistake. Trace a loop that breaks at i == 3 and say exactly what prints.

Let's take this on the board with one tiny Main class — no extra files. Java Break — output: 1 then 2. When i is 3, break stops the loop — 4 and 5 never print. Start from main, go line by line, and stop at each print. That output is the proof for Break.

Exam tip

Trace break at i == 3. Say what prints.

Example

// Java Break
public class Main {
  public static void main(String[] args) {
    for (int i = 1; i <= 5; i++) {
      if (i == 3) {
        break;
      }
      System.out.println(i);
    }
  }
}

Java Break — output: 1 then 2. When i is 3, break stops the loop — 4 and 5 never print.

Short notes

Defbreak leaves the nearest loop or switch right now.
RuleIn nested loops, plain break exits only the inner loop.
Diffcontinue skips one round. break ends the loop.
UseStop early when the answer is found.
